Abstract
An LCD device includes a transparent glass plate 122 and thin film transistor electrodes 124 formed on the glass plate 122. A photosensitive insulation film 128 is coated on the glass plate 122 and the thin film transistor electrodes 124. The insulation film 128 includes transparent and reflective regions 134 and 133 which are different in thickness. Light shielding films 126 are positioned underneath boundaries of the transparent and reflective regions 134 and 133. Where an optical exposure stage includes different reflection coefficient portions, the light shielding films 126 prevent light reflected by the exposure stage from reaching the insulation film thereby maintaining the accuracy of its patterning.
